最近使用slam的时候编译经常遇到问题，解决在这篇文章中
依赖项：

sudo apt install libglew-dev

安装pangolin：

# 下载Pangolin
git https://github.com/stevenlovegrove/Pangolin.git
# 编译
cd Pangolin
mkdir build  &&cd build 
cmake .. && make
sudo make install

这样安装后一直遇到问题：

In file included from /usr/local/include/pangolin/gl/gl.h:324:0,
                 from /usr/local/include/pangolin/handler/handler.h:31,
                 from /usr/local/include/pangolin/display/widgets.h:32,
                 from /usr/local/include/pangolin/pangolin.h:40,
                 from /home/marcos/code/SensorsCalibration/lidar2camera/manual_calib/src/run_lidar2camera.cpp:9:
/usr/local/include/pangolin/gl/gl.hpp: In member function ‘void pangolin::GlTexture::CopyFrom(const pangolin::GlTexture&)’:
/usr/local/include/pangolin/gl/gl.hpp:348:5: error: ‘glCopyImageSubDataNV’ was not declared in this scope
     glCopyImageSubDataNV(tex.tid, GL_TEXTURE_2D, 0, 0, 0, 0,
     ^~~~~~~~~~~~~~~~~~~~
/usr/local/include/pangolin/gl/gl.hpp:348:5: note: suggested alternative: ‘glCopyColorSubTable’
     glCopyImageSubDataNV(tex.tid, GL_TEXTURE_2D, 0, 0, 0, 0,
     ^~~~~~~~~~~~~~~~~~~~
     glCopyColorSubTable

其实也很明显，这是pangolin版本不对，然后我就去换了0.9 0.8 0.7 版本都不行，最后发现得是0.6：

所以得先卸载一下pangolin，所有三方库都可以通过这个方法来卸载，首先：

cd Pangolin/build
make clean
sudo make uninstall

然后删除源码文件：

sudo rm -r Pangolin

找到usr里面的库文件位置：

sudo updatedb
locate pangolin

然后删除相应的文件夹：

sudo rm -r /usr/local/include/pangolin

再次检查一下：

sudo updatedb
locate pangolin

然后重新去安装：

git https://github.com/stevenlovegrove/Pangolin.git
cd Pangolin
git checkout v0.6
mkdir build && cd build
cmake ..
cmake --build .
sudo make install

这样就大功告成了，不需要去修改原本项目的CMakeLists.txt就能编译成功了。
